What's the weather like in Japan in July?

The climate zone in Japan can be divided into: 1. Hokkaido climate zone (cool in summer and cold in winter, less precipitation, less affected by plum rains and typhoons). 2. Coastal climate zone of the Sea of Japan (snowy in winter and sunny in summer). 3. Inland climate zone (affected by monsoon, with less precipitation and large temperature difference between Xia Dong and day and night). 4. Climatic zone along the Pacific coast (influenced by the ocean, rainy in summer, hot and foggy, warm in winter, mostly influenced by typhoons). 5. Seto inland sea climate zone (surrounded by mountains on all sides, sunny days and little rain) and southwest islands climate zone (high temperature and no frost and snow). For example, it's about 22-30 degrees in Tokyo in July.
